This high vacuum oil purifier performs the function of upgrading and reconditioning of insulating transformer oil by means of removing impurities such as dust,gas,sludge,water etc. The major operation is heating, filtering, degassing and dehydration. After recycling, it can boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which have insulation system. Tongrui ZJA series specialize in purifying transformer oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is also suitable for treating low viscosity lubrication oil.

Advantages:

1.With roots booster pump system, the secondary high vacuum air extracting system for rapidly removal of gas and moisture. processing is equivalent to two units common vacuum purifier.

2.High extraction speed double vacuuming systems which is able to utmostly enhance the vacuum environment of internal

vacuum tank to make high vacuum. Ultimate vacuum ≤5Pa, working vacuum ≤35Pa.

3.After filtration, the dielectric strength and flash point is higher, after one cycle of filtration, breakdown voltage increases 3-5kv,
